If you want to follow the totally made up sayings of the Quran, fine, that's your right to do so.
BUT, keep in mind that not one word of it was written until AFTER Mohhammed died. There is absolutely NO proof of any type that any of it was either said by him, or by God.
It has more contradictions than the Bible does, by far. Either that, or virtually every Iman in the world is wrong, when they preach Jihad against the Jews and Christians. I say that, because the Quran REQUIRES that all people of the BOOK must be treated with respect.
You do NOT treat people with respect by murdering them. You do not treat such people with respect by forcing them to convert to your religion or die (as all of your religion was spread "by the sword", your own religion violated its own holy book).
And you can NOT keep your belief in Jesus if you join Islam. Because, to Christians, Jesus is the Son of God, one of the Trinity. And I hate to tell you, but you can not possibly get any "Prophet" on the same level, much less a higher level, than God himself. Jesus IS God, just as is the Father and the Holy Spirit.
